Problem: UV light does not light up or self-extinguishes
Cause of failure 1: UV lamp aging. Solution: Replace the UV lamp.
Cause of failure 2: The power supply voltage is lower than 10%. Solution: Increase the voltage.
Cause of failure 3: Insufficient air cooling. Solution: Clear the air duct and clean the fan wheel and debris.
Problem: The UV machine cannot shut down automatically after all the UV lights are turned off.
Cause of failure: The delayer is damaged. Solution: Replace the delayer.
question: UV machine mesh belt deviation
Cause of failure: The mesh belt is unevenly tight on the left and right sides. Solution: Readjust the mesh belt adjustment screw.
question: There is control power, but the lights cannot be turned on and the abnormal light on the control panel does not light up.
Cause of failure 1: The UV lamp is old or deteriorated. Solution: Replace the UV lamp.
Cause of failure 2: The main circuit fuse is blown. Solution: Check and replace the main circuit fuse. Check whether the main circuit line is loose and short-circuited to ground, check whether the main transformer of the UV equipment is faulty, and check whether the capacitor is faulty.
question: Unable to automatically switch between full and half lights
Cause of the fault: The linkage signal with the printing press was abnormal, and the manual and automatic mode switches were not switched to the automatic position. Solution: Check whether the signal line to the printing machine is not connected, broken or loose.
question: Transformer temperature is too high
Cause of failure 1: The power supply voltage is higher than 10%. Solution: Reduce the input voltage of the machine and enhance ventilation.
Cause of failure 2: Poor ventilation around the machine. Solution: Clean and dredge the environment around the machine to ensure smooth ventilation.
